Title: Fine dust filter band collecting cyclone air - forms internal chamber from which collected dust is blown and sucked
Inventor: KRAEMER ERICH
IPC: B01D46/18
Filed: 1989-08-10
Abstract: Air contg. residual fine powder, esp air emerging from a cyclone for cleaning air from particle spray plant, enters (14) a chamber (12) in which a continuous filter bond (18) passes over an assembly of rollers. Into the space (22) bounded by the band is inserted the end (24) of a suction line, connected esp to a  blower; the reduced pressure is the internal space sacks away fine powder accumulating on the filter band. To reinforce the dust removal effect, compressed air from an external source (32) is blown into a domed bell (30) engaging the filter band, and forcing dust from the other side of the band into a collector bag (40). A further bell (26) may be applied to this other side. ADVANTAGE: With considerable total filter surface area, combined air suctions and pressure effectively remove collected dust.

Patent DE-4001213-A1 (DE)
Inventor: WOLF ERICH
IPC: B24B5/36
Filed: 1990-01-17
Abstract: The invention relates to a means for removing protruding parts, such as protuberances, burrs and the like, from tyres (4) and similar articles (trimming means) by embrittling and breaking these parts, it being possible to process tyres of different sizes one after the other as desired in an unordered manner, the means having a mounting frame or a housing, which contains a cold-embrittling device (3), i.e. a cooling device, and a breaking tool as well as devices which accomplish the individual separation, clamping, transporting and processing movement of the tyres in the housing. Problems in neatly removing the protruding parts over the entire tyre contour are solved by the installation according to the invention in that a ribbed non-rigid band (20), comprising connected individual elements or a wire mesh or the like, is suspended as the breaking tool in the mounting frame or housing in such a way, for example in a liquid nitrogen bath representing the embrittling device, that the cold-embrittled tyres are able to be brought with the treads up to this band (20), the band leaning against the respective tyre profile and consequently, due to the processing movement of the tyre, preferably a rotation, the protruding parts being broken off.

IPC: C03B11/08
Filed: 1990-01-30
Abstract: In the prodn. of a mould for forming a press moulded glass article, involving forming an i-carbon film on the mould face by an ion coating process, the novelty is that ion coating is effected in an appts. with an anode, a first cathode, a mould holder and a reflector which extends to the vicinity of the mould holder and surrounds both electrodes.

Title: Telephone installation for main line or PBX working - has console with cradles for cordless and cord-connected handsets
Inventor: SCHARN HANNELORE
IPC: H04M1/725
Filed: 1990-08-18
Abstract: The subscriber's premises installation consists of a console (1) for two handsets (2,3) one of which is cordless (3).

The console keyboard then serves to switch through calls with characteristic call tones, the call sound for the PBX operation being different from the external calls. A plug (6) serves for exchange line or internal tone connections using the official telephone company socket (5). If a call is switched over to the cordless handset another call can be received by the cord-connected one. USE/ADVANTAGE - Compact, economic combination for internal and exchange line working.
Patent DE-4038486-A1 (DE)
IPC: B27L5/06
Filed: 1990-12-03
Abstract: A machine for severing a board, by means of cutting, from a squared timber (14) which is advanced in its longitudinal direction against a cutter (12) and is pressed against the cutter from the side facing away from the cutter by means of a pressure device (18) and against a counterpressure rail mounted upstream of said cutter is described. In contrast to conventional designs in which the driven feed rollers for the squared timber are arranged in front of and behind the actual cutting device, according to the invention driven feed-roller pairs (32a/34a) are provided directly in the extension region of the cutter forming a very acute angle with the feed direction of the timber. In addition, the feed-roller pairs are mounted in a floating manner, so that they do not influence the position of the squared timber. As a result of the novel arrangement, an excessively long force-transmission path through the squared timber itself, from the feed rollers to the cutter, is avoided. <IMAGE>

Title: System for determining and monitoring preset filling level in container - has piezoelectric vibration system with sensor for contacting filling medium in container if preset level is exceeded and evaluation circuit producing signal depending upon amplifier output frequency.
Inventor: DREYER VOLKER
IPC: G01F23/296
Filed: 1992-02-11
Abstract: The excitation system produces a mechanical vibration. The system includes a piezoelectric converter (65) excited by an AC voltage and a piezoelectric receiver converter (66), which converts the vibration in to an electrical output signal. This signal is fed to an amplifier circuit. The output of this circuit is supplied to the excitation converter (65), to produce vibrations with its characteristic resonance frequency. An evaluation circuit (73) is connected to the output of the amplifier circuit (70, 71, 72) so that its output signal assumes one or another of two conditions, depending on whether the frequency of the amplifier circuit output signal exceeds or undershoots an adjusted reference frequency. A voltage lowering circuit controlled by the output signal of the evaluation circuit, lowers the AC voltage applied at the excitation converter (65) from the amplifier circuit, if the output signal of the evaluation circuit has the condition, which corresponds to the exceeding of the set reference frequency. ADVANTAGE - System has reduced noise level with good signal-noise ratio.
